LIGHT COMPANY, OF DAYTON, OHIO, A CORPORATION DAYTON, OHIO, ASSIGNORS TODELCO- OF DELAWARE PUMP Application tiled O ctober 25, 1926. ISerial No.143,822.

This invention relates to improvements in a pumping device andparticularly to that type of pumping device which includes a pumpoperatively. connected with a pump' operating mechanism, said pumpoperating mechanism being driven by a power device by means of a belt.

It is among the objects ofthe present invention to simplify the mountingof the pump. its operating mechanism and the power device, so that thepump and its (ip-.-

erating mechanism are rigidly secured 1n proper relation. The powerdevice is so mounted that it may be adjusted to vary the tension of thebelt connecting v.it with the pump operating mechanism, whilemaintaining the alignment between these two elements. A further objectis to provide the pump operating mechanism with an improved lubricatingdevice which will provide lubricant in proper amounts to the movingelementsthereof.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings, wherein a preferred form of embodiment of the presentinvention is clearly shown.

Referring to the drawings and more particularly .to Fig. 1 the numeral20 designates a pump having a cylinder 21 from which extends a pump rod22. The pump has a flange 23 to which is secured the water tank 24. Thecylinder 21 cent these feet the cylinder housing has a lug providing twoparallel sides for purposes to: i

has a plurality of feet 25 extending from each side thereof, and adjathe housing there are provided two lugs 35 I and 36, the outer surfacesof which are pari allel and spaced the same distance as the parallelthe-pump. Atthe end of housing 31, oppo-` site opening 33, there isprovided another opening 37 of lesser size however than the opening 33.In this opening 37 there is provided a cover 38 having a packing gland39 associated therewith. f

Inside the housing 31 there is provided a` cylinder 40 coaxial with theopening 37. Above the cylinder 40 and within the housing sides of thecylinder housing 31 of 31 .there is located a pocket 41 whichcommunicates with the inside of the cylinder by means of vaperture 42.An upwardly sloping shelf 43 formed on the end of the cylinder andextending across the housing provides an entrance to this pocket inclose proximity to the path of travel of an oil thrower ,to be describedhereinafter.

a piston 44 being connected with one end of the connecting rod 45 bymeans of wrist pin' Within the cylinder 40 there is provided l 46. vAsshown in Figs. 1 and 5 the rod 22 extends from the pump, through thepacking gland 39 of the pump operating member, and

has its screw-threaded end secured to the head j of the piston 44.Intermediate t-he pump and the pump operating members the rod 22 has adisc portion 22a, adapted .to be gripped by the tool for screwing therod into the piston 44. On one side of the housing 31 there mil isprovided anextension 48 in whichsthere is fitted a bearing 49 forsupporting the drive shaft 50. On the outside end of .this shaft thereis secured a pulley 51 adapted to receife the belt 52. On the oppositeend of this shaft and inside the housing 31 there is secured vraneccentric 53'which is operatively connected to the strap port-ion 54 ofthe conneet-ing rod 45.

Attached to one side of the eccentric is a fan-shaped plate 55 having aplurality' of angular extensions 56. This plate is detailedly shown-inFig. 7 and is of such a conformation and so mounted on the eccentricthat as the eccentric rotates the extensions 56 will dip j movein closeproximity to the said dished shelf as the eccentric rotates. The dishedshelf has a passageway 61 communicating therewith which leads to anaperture 62 communicating in turn with the bearing 49 of shaft 50. In'Fig. 6 it may be seen that the pocket 41, adapted to receive lubricantand deliver the same to the cylinder 40 and `piston 44, is in directalignment with and in the plane of operation of the eccentric 53. It mayalso be seen that the dished shelf 60 lies by the side'of the disc 55carried by the eccentric 53.

When the pump operating device included in the housing 31 is operated bythe rotation of the pulley 51 the shaft 50 will be rotated thus causingthe eccentric 53 to reciprocate the piston 44 in the cylinder 40,consequently causing reciprocation in pump rod 22. Rotation of eccentric53 will cause the extensions 56 of plate 55 to dip into the oi-l andpick up a certain amount thereof, and, due to centrifugal force the oilwill be thrown straight forward into the pocket 4l to lubricate thepiston and cylinder and due to the formation of the angular extension 56lthe oil will be thrown sidewise against the wall of thev crankcase andthen the oil will flow down said wall into the dished shelf 60 fromwhence it will How through passageway 61 and aperture 62 to lubricatethe shaft 50. The pocket 41 and the dished -.Lelf 60 will consequentlyreceive an oil supply directly from the oil throwing plate 55. Y

As has been mentioned before, the pump and the pump operating mechanisminclude parallel sides on the outside of their casings. To these sidesare attached angle irons 7 O and 71 whichform a support for the entirepump Qassembly -including the power device. At ythe pump operatingmechanism end of the angle irons and 1 there is provided a 'foot 72which .engages the outside of the vertical gether also secure the oneend of the foot 76 to the angle irons. The opposite end of the foot 76is secured to the angle iron by means of the short bolts 77 provided ineach angle iron. The purpose of this will be described hereinafter.

As shown in Fig. 1 the angle irons 70 and 71 extend beyond the foot 76,and are held Aparallel due tothe fact that they are secured to theparallel and equally spaced sides of the pump and pump operatingmechanism.

Referring to Figs. 2 and 3, the method of attaching the power device80', shown in the form of an electric motor, is clearly illustrated. Theelectric motor is provided with the ordinary standard base 81 to whichis attached a guide member 82 by means of studs 83. The ends of theguide member are upturned as at 84, the edges thereof engaging Vwith thebottomy of the base 81 of the motor.

This guide member 82 is of a width equal to the distance between theparallel sides of the pump and thus said guide member slidably fitsbetween the vertical arms of the angle irons. The sides of the guidemember adjacent the angle irons are open and a clamping bolt 85 extendstransversely therethrough thus permitting the guide member to be slippedback and forth between the angle irons foi` the purpose of adjusting thebelt 52. The front end of the guide member is cut away topermitclearance forthe head of bolts 77. The clamping bolt 85 has a head 87engaging with the angle iron 71 while at the other end there is provideda nut 88 adapted to .be screwed against the vertical angle iron 70 forsimultaneously clamplng the angle" irons 70 and 71 and the guide member82 together. By loosening this nut y88 the motor withits guide member 82may be slid back and forth along the angle irons for the purpose ofadjusting the tension of belt 52. By this structure adjustments may bemade with- -out effecting the alignment between the pulleys 51 and 86 ofthe pump drivin mechanisrn and the motor respectively. fter the guidemember 82 is once secured in correct alignment on the motor base 81 itneed not be removed even when it is desired to remove .the motor fromthe angle irons for any purf 23 of the pump. A small lug or extension 90is provided on the pump operating mechamsm, normally in Ispaced relationwith the tank 24 to permit easy application of the tank to the iange23,y however, providing a sup- :.\port for said tank if any undue loadbe placed thereon which support would substantially prevent anystrain'on the liange 23.
